Pettex Aquatics Reptile Substrates are the ideal way to set up a reptile’s home. When you need to make a reptile happy and comfortable there’s a substrate available to replicate their natural habitats. We only use carefully selected substrates from around the world from sustainable and renewable sources. All substrates are heat treated and sanitised for guaranteed safety and performance. It is essential to choose the right substrate so as not to cause reptiles any undue stress. Some of the substrates will work wonders for reptiles that dig and burrow, while others are simply for walking on.
